Question EGVA p/n: 141-BL-E757-TR

Hello All

I have a EGVA motherboard with a bad diode. The board component number is D11. Does anyone know the part value for this board? EGVA was no help.

Thanks As Always,
Lcdman

Hello Again,

Can I just use any three legged diode to replace this one? And no its noted on the board as a diode (D) not a transistor (Q). Anyone want to chime in on this?

Thanks

You should trace what circuit/chip it goes to so we can figure it out.

There are many types of SOT-23 diode configurations available - i.e. which pin is Anode/Cathode and whether there are 1 or 2 diodes in that device (since it does have 3 pins). Getting the wrong diode could cause further damage in the circuit, so that's why we have to find out what it should be.

I see it's near Q68, so at this point, I can only assume it possibly has something to do with being part of the RAM voltage regulator circuit.
